Tires

[FutureRacer]

Is it possible to put 20-11-9 tires in replace of my 20-10-9 old stock tires on my stock rims?
Its a 2002 Honda 400ex, the stock tires are still on it, but its bout time for new ones, can I put a whole inch wider tire on it? This might be a dumb question, im not really sure, I would appreciate any help given. Thanks, Kelley

Yes. Just always make sure the rim size is the same, in this case 9"

yea all the other #s dont really matter but the last # has to mach (9)
